Higher Taxonomy
Family: BerberidaceaeView DescriptionDichotomous Key
Common Name: BARBERRY FAMILY
Habit: Perennial herb, shrub, [tree], generally rhizomed, caudexed or not, glabrous, glaucous, or hairy. Stem: spreading to erect, branched or not. Leaf: simple, 1--3-ternate, or pinnately compound, basal and cauline, generally alternate, deciduous or evergreen, petioled, stipuled. Inflorescence: generally raceme, spike, or panicle, scapose, terminal, or axillary. Flower: generally bisexual, radial; sepals 6--18 or 0, generally in whorls of 3; petals generally 6, in 2 whorls of 3, or 0; stamens 6--12(13), free or fused at base, in 2 whorls or not, anthers dehiscent by flap-like valves or longitudinal slits; ovary superior, chamber 1, ovules generally 1--10, style 1 or 0, stigma flat or spheric. Fruit: berry, capsule, achene [follicle].
Genera In Family: 16 genera, +- 670 species: temperate, tropics worldwide; some cultivated (Berberis, Epimedium, Nandina (heavenly bamboo), Vancouveria). Note: Lower sepals sometimes called "bracteoles," inner petals "staminodes".

Genus: VancouveriaView DescriptionDichotomous Key


Common Name: INSIDE-OUT-FLOWER
Habit: Perennial herb, rhizomes extensive, scales brown. Stem: 0. Leaf: basal, long-petioled, 2--3-ternate; leaflet blades ovate to +- cordate, lobes 3, shallow, teeth 0 or shallow. Inflorescence: raceme or panicle, +- scapose, open, long-peduncled; flowers spreading to pendent. Flower: sepals generally 12--15, 8--9 mm, outer 6--9 << inner 6, bract-like, deciduous, inner petal-like, persistent, in age reflexed; petals 6, < inner sepals, reflexed from base, distally glandular; stamens generally 6, held against ovary, style, anther valves flap-like, pointed tipward; ovules 2--10, style 1, < ovary, persistent, beak-like in fruit, stigma cup-like. Fruit: capsule, 2-valved, generally elliptic. Seed: with oily body for ant dispersal.
Etymology: (Captain George Vancouver, British explorer, 1757--1798) Note: Pedicel appears to arise from inside flower, from tip instead of base, yielding an upside-down or "inside-out" flower.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
